Jacinda Ardern has admitted she's yet to watch the latest season of her own partner's TV show.

Clarke Gayford hosts Fish of the Day, which airs on Prime and will move to Three in 2019. But the Prime Minister's had a busy year.

"It is a bit of a sore point for him, but I did see all of season one," she told RadioLIVE on Friday morning. "But season two of his show, I haven't really seen as much."

Ms Ardern has a pretty good excuse, having become a mother for the first time in addition to running the country. Neve Te Aroha Ardern Gayford was born in June.

"The only period where I really watched any television was right before I was waiting for Neve to arrive," said Ms Ardern.

"When I say 'arrive', I mean actually when I was in labour, I started watching a bit of Netflix... there's some good crime shows on Netflix. But since Neve's arrived I actually haven't been able to watch anything like that."
